Okay so in June of 2018 I went through a bad breakup with my BD and started a relationship with this guy (we will call him Jimmy) who happened to be the brother of my best friends friend. (we can call her Amy and him James)

Long story short we dated for a while (about 8 months) in that tome frame i for pregnant and miscarried. That caused a lot of strain on our relationship and we ended up splitting.

During our time together James and i became friends. So we chat here and there but not too much.

Well a few months ago Amy and James started sleeping each other and Amy developed feelings when James just wanted to be Fwb.

Now Amy has asked me and James if we would mind if her and Jimmy started talking.

I told her i didnt mind because i dont have feelings for him and i know he would treat her and her kids right it was just a little weird. So i reached out to James and asked him how he felt about about them and he said it was weird but he would have to get over it.

I talked to Amy about it who told Jimmy about it and now he is upset with me for speaking to his brother. Like im not allowed to talk to him at all. He told her to just hang up on me and that i need to leave them alone. I asked her what her response was to that and she said it made her mad and she wanted him to leave but she didnt say anything? So im starting to think she's riding the fence on us both or me at least

Am i wrong? Im upset only because

If me and James are friends and the ones they were so concerned about why couldnt we have a conversation about it?

Now i just have a feeling its going to end badly because Jimmy obviously has an issue with me but hes with my best friend. Thats not new news to him. We've been friends for over 10 years.

So what would you do?
